Weir NS-3 simulator

This is an NS-3 simulator for Weir. It is based on the NS3 simulation of HPCC and the NS3 simulation of Floodgate.

Quick Start

Build

./waf -d optimized configure

./waf build

Please note if gcc version > 5, compilation will fail due to some ns3 code style. If this what you encounter, please use:

CC='gcc-5' CXX='g++-5' ./waf configure

Run

The direct command to run is: ./waf --run 'third mix/config-dcqcn.ini'
